Giant Apatosaurus on a Prehistoric Plain
A giant Apatosaurus stands on a broad swampy plain. The prehistoric environment features primitive cycad plants, a calm pond, and a towering rocky cliff in the background. As one of the largest land animals of the Jurassic Period, Apatosaurus inhabited humid river valleys and lush floodplains rich in plant life.
Life of the Long-Necked Apatosaurus
Apatosaurus was a massive herbivorous dinosaur that reached lengths of seventy-five feet and weighed over twenty tons. Its long, flexible neck enabled it to sweep across vast areas to feed on ferns, horsetails, and palm-like cycads without moving its heavy body. Scientists believe Apatosaurus swallowed smooth stones called gastroliths to help grind tough plant fibers inside its stomach.
